According to Moose's trivia video about the new 800 mm F5.6 AFS, the VR is completely silent. Unlike all the other super telephotos where the VR makes a whirring noise, this new $18k baby is quiet for video shooters.

Now, here's the question, is Nikon going to revamp all of their existing VRII lenses with this new mechanism so they too will be quiet as a church mouse for those of us shooting video?

Well the marketing department would like us all to believe it is the same VR unit so we'll purchase current models of the 300, 400, 500, and 600. But as Moose points out, it is totally silent so something internal has changed.
